### Step 9: Perform a Test Measurement

At this point, do a test measurement to ensure that everything is set up correctly and to see if the accuracy is good.

1. Use a test part, something like a 700 mm sized test block.

2. Tilt the part in 3D space.

3. Measure the part using an alignment.

4. Reposition it in different locations inside the machine volume.

5. Measure with a single arm.

6. Measure with both arms.

7. Compare the results against measurements done on separate, single-arm machines.

The next step provides information on mapping the other extensions.
